I am using Apache Camel 2.16.0 with Spring DSL
I have a Spring context XML in which I have defined a Property PlaceHolder to read the properties from various files as follows-
<bean id="propertyPlaceholder" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
<property name="ignoreResourceNotFound" value="false"/>
<property name="locations">
<list>
<value>classpath:/properties/versioning.properties</value>
<value>classpath:/properties/#{inetAddress.hostName}.properties</value>
</list>
</property>
</bean>
<bean id="inetAddress" class="java.net.InetAddress" factory-method="getLocalHost"/>
The property values are used to construct other beans such as -
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="org.gjt.mm.mysql.Driver"/>
<property name="url" value="${${LIVE_}DATASOURCE_URL}"/>
<property name="username" value="${${LIVE_}DATASOURCE_USERNAME}"/>
<property name="password" value="${${LIVE_}DATASOURCE_PASSWORD}"/>
</bean>
This works fine, I can see the beans being created.
I also have another Spring Context XML in the same app which has a camel context and I want to use the some other properties defined in the same properties files. I know that camel supports Spring Property Placeholder, see below excerpts from the context -
<camelContext id="charge-process-context" xmlns="http://camel.apache.org/schema/spring">
<propertyPlaceholder id="properties"
location="classpath:/properties/versioning.properties,
properties/${env:HOSTNAME}.properties"
xmlns="http://camel.apache.org/schema/spring" />
.....
.....
</camelContext>
As part of this context, I have a route that uses https component that uses the values from the property file such as below -
<to uri="https4:{{LIVE_AUTH_RESPONSE_HOST}}:{{LIVE_AUTH_RESPONSE_PORT}}/{{LIVE_AUTH_RESPONSE_CONTEXT_PATH}}"/>
This route does not start and throws following exception -

Please Note: I am deploying my application as a war file on Tomcat 8 on an AWS instance.
I have a Dev Environment on Windows 10 and I have found this working on the Windows OS. I have also seen that the file FilePathResolver.java in Apache Camel 2.16 uses System.getenv(key) to obtain the value i.e. System.getenv("HOSTNAME") which returns a null on AWS instance and a correct value on Windows 10. I also tried using env:hostname (small case letters for unix) but still no luck ...
I found a solution at http://camel.apache.org/using-propertyplaceholder.html
at Bridging Spring and Camel Property Placeholders
It mentions following -
The Spring Framework does not allow 3rd party frameworks such as Apache Camel to seamless hook into the Spring property placeholder mechanism. However you can easily bridge Spring and Camel by declaring a Spring bean with the type org.apache.camel.spring.spi.BridgePropertyPlaceholderConfigurer, which is a Spring org.springframework.beans.factory.config.PropertyPlaceholderConfigurer type.

After upgrade from Spring 5.2.x to 5.3.x, the error message DispatcherServlet.noHandlerFound Message=No mapping for GET /sampler/
Sample code -- https://github.com/hth/sampler working fine with 5.2.12 lib
This may be related to a change where additional beans are registered with the DispatcherServlet.
Specifically, the DefaultRequestToViewNameTranslator bean is now loaded in 5.3.x, which may be transforming the URI to a view name.
You may be able to disable this behavior by setting the stripLeadingSlash, stripExtension, and stripTrailingSlash properties to false.
Try adding the following bean definition to your root-context.xml file.
<bean id="viewNameTranslator" class="org.springframework.web.servlet.view.DefaultRequestToViewNameTranslator">
<property name="stripLeadingSlash" value="false" />
<property name="stripExtension" value="false" />
<property name="stripTrailingSlash" value="false" />
</bean>
I am using jasypt 1.9.2 to encrypt a password in a property file for my spring REST service. I've added an environment variable to Weblogic via the Server startup arguments text box called APP_ENCRYTPION_PASSWORD, but that environment variable is not getting read by the jasypt. Here is the error:
ERROR o.s.web.servlet.DispatcherServlet - Context initialization failed
java.lang.NullPointerException: null
at org .jasypt.encryption.pbe.config.SimplePBEConfig.getPasswordCharArray(SimplePBEConfig.java:434) ~[jasypt-1.9.2.jar:na]
Here is the Weblogic environment variable logged during when the server starts up:
JAVA_OPTIONS= -Dother.vars=xxx -DAPP_ENCRYPTION_PASSWORD=password -Dmore.vars=yyy
I've traced the jasypt code and it seems jasypt does not parse the environment variables within JAVA_OPTIONS. I know this works for other frameworks like spring since we have other environment variables within JAVA_OPTIONS that spring has no issue reading.
I could add the environment variable to the startup scripts (setEnv.sh I think) for weblogic, but that will add the variable for all managed nodes instead of the one cluster my app is deployed to.
Is there a different way to configure jasypt within spring to get the environment variables within JAVA_OPTIONS?
Here is my spring config:
<bean
class="org.jasypt.spring31.properties.EncryptablePropertyPlaceholderConfigurer">
<constructor-arg>
<bean class="org.jasypt.encryption.pbe.StandardPBEStringEncryptor">
<property name="config">
<bean class="org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig">
<property name="algorithm" value="PBEWithMD5AndTripleDES" />
<property name="passwordEnvName" value="APP_ENCRYPTION_PASSWORD" />
</bean>
</property>
</bean>
</constructor-arg>
<property name="location">
<value>application.properties
</value>
</property>
</bean>
My application.properties file contents:
username=someuser
password=ENC(encryptedstring)
UPDATE for clarity:
Adding the environment variable to weblogic via setEnv.sh or Eclipse works just fine. It's only when I use the weblogic console to add the environment variable for a cluster that jasypt fails to parse the value since it is within JAVA_OPTIONS.
You can use passwordSysPropertyName instead of passwordEnvName. This way you can use -DpasswordSysPropertyName="mysecret"
<bean id="environmentVariablesConfiguration"
class="org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig">
<property name="algorithm" value="PBEWithMD5AndDES" />
<property name="passwordSysPropertyName" value="APP_ENCRYPTION_PASSWORD" />
</bean>
I tested a ActiveMQ 5.5.0 (fuse version) app in AMQ 5.6.0 and noticed that our Spring JNDI configured Oracle datasources aren't being found.
The only thing I changed in my applications was the pom.xml versions of AMQ/Spring (to match the 5.6 versions). Otherwise, I'm using the identical application code and configuration (activemq.xml, jndi.xml, etc), but my Spring JDBC DAOs (v3.0.5) are failing to find them.
No errors in the logs otherwise, just this Spring Application Context initialization error...
javax.naming.NameNotFoundException; remaining name 'jdbc/myDataSource'
here is the relevant Spring jndi config (conf/jndi.xml, included in conf/activemq.xml)...
<bean id="jndi" class="org.apache.xbean.spring.jndi.SpringInitialContextFactory"
factory-method="makeInitialContext" scope="singleton">
<property name="entries" ref="jndiEntries" />
</bean>
<util:map id="jndiEntries">
<entry key="jdbc/myDataSource">
<bean id="myDBCPDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.OracleDriver" />
...
then my application references it like this...
<bean id="myDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>jdbc/myDataSource</value>
</property>
</bean>
<bean id="messageDAO" class="com.mycompany.MessageDAOImpl">
<property name="dataSource" ref="myDataSource" />
</bean>
That said, I tested without using JNDI (instead just hardcoded the datasource in my app) and everything works as expected. So that should rule out everything except the Spring JNDI registration/lookup of the datasource, etc.
So, what am I missing?
ActiveMQ has a dependency into xbean-spring, which you are using as a JNDI provider. It is likely that the transitive Xbean dependency has changed because of the upgrade to ActiveMQ 5.6.0.
I found the issue, I added a jndi.properties file under the /conf directory containing the following and it works fine now (didn't need this under AMQ 5.5...strange)...
java.naming.factory.initial = org.apache.xbean.spring.jndi.SpringInitialContextFactory
I have an application deployed into Oracle Weblogic 10.3. In my .ear files, I use spring injection from xml files in the ear files. I would like to also perform dependency injection from xml files placed on the server file-system. We do something similar to this in Karaf, where we place our configuration files for bundles in the conf directory in the server itself. Is there a similar way to do this in weblogic?
You can ask spring to read properties from file systems as below;
<!-- Reads application properties and uses them in the application context -->
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="ignoreResourceNotFound" value="true"/>
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
<property name="locations">
<list>
<value>file:D:\somefolder\application.properties</value>
<value>classpath:com/foo/sp.properties</value>
</list>
</property>
</bean>
I want to pass the WSDL url for an internal web service into my Spring beans.xml dynamically, using a PropertyPlaceHolderConfigurer.
Here's the scenario:
My web application is deployed in WebLogic 10.3.
The WSDL url is contained in a properties file that is located outside my application (directly under the corresponding domain folder, while my application is inside the autodeploy folder). I set the location of this properties file in my domain's setDomainEnv.cmd file like below:
set JAVA_PROPERTIES=%JAVA_PROPERTIES% %CLUSTER_PROPERTIES% -Dproperty.file.path.config=%DOMAIN_HOME%\Service.properties
This is what my Service.properties file contains:
Service.WSDL.PATH=http://localhost:8088/mockServiceSoap?WSDL
My Spring beans.xml configuration:----
<bean id="file.path" class="java.lang.System" factory-method="getProperty">
<constructor-arg index="0"><value>property.file.path.config</value></constructor-arg>
</bean>
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" ref="file.path"/>
</bean>
<bean id="myServiceId" class="com.test.service.ServiceImpl">
<property name="myServiceSoap">
<ref bean="myService"/>
</property>
</bean>
<bean id="myService" class="org.springframework.remoting.jaxws.JaxWsPortProxyFactoryBean">
<property name="serviceInterface" value="com.test.service.ServiceSoap"/>
<property name="wsdlDocumentUrl" value="${Service.WSDL.PATH}"/>
</bean>
I enabled DEBUG log specifically for PPC and this is what I saw in my application log:
INFO org.springframework.beans.factory.config.PropertyPlaceholderConfigurer 178 - Loading properties file from URL [file:D:/bea10.3/user_projects/domains/my_domain/Service.properties]
So, it seems that although the Service.properties file is getting loaded by PPC, the ${Service.WSDL.PATH} is NOT getting replaced.
What am I doing wrong here?
Also, how can I find out if PPC tried replacing the value of the placeholder and with what value? I was hoping the log file would contain that info but there was nothing there.
Any help is appreciated.
I've figured out, that PropertyPlaceholderConfigurer needs to be declared first in the application Context file, otherwise there's no guarantee of the load order. It took me a few hours to realize this.
Try moving the "file.path" bean into the PropertyPlaceHolderConfigurer's location property.
